Summary

On require(), index.js serializes the full process.env along with hostname, username, homedir, platform, and cwd, base64-encodes the JSON blob, and transmits it via HTTPS GET to api.telegram.org using a hardcoded bot token (7231970337) and chat_id (8969499041). A flag file under the OS tmpdir suppresses repeat sends. The package advertises itself as a 'drop-in replacement for bip39' and lazily re-exports the real bip39 module when present, otherwise returning stub wallet/mnemonic functions, positioning it as a typosquat aimed at cryptocurrency developers. process.env in developer and CI environments typically contains API tokens, cloud credentials, and publish tokens, which are exfiltrated on first import.
